ABSTRACT:
A connector of the nut-and-bolt type with a bolt that has an external thread and/or a nut that has an internal thread. The connector has a locking device that provides a moment of friction that counteracts the unscrewing moment. The pitch of the external thread differs from that of the internal thread. The external thread is screwed far enough into the internal thread or vice versa for the moment of friction of the locking device to result, once the flank clearance between the two threads has been completely occupied and exceeded, from the forces that occur during resilient deformation.
